Abstract

Flexible, porous, absorbent polymeric macrostructures having flexibility even after extended periods at elevated temperatures and/or low humidities are disclosed. The macrostructure comprises an interparticle crosslinked aggregate and an effective amount of a suitable plasticizer. The macrostructures are suitable for use, for example, in disposable absorbent articles such as diapers.
